| The durability and cost are two most critical issues in the process of commercialization for Proton Exchange Membrane Fuel Cell. But the durability test has two chatacteristics:high cost and prolonged testing periods.These factors led to the durability of fuel cell research makes the slow development. The corrosion mechanism and performance degradation of main materials in proton exchange membrane fuel cell fuel were studyed under open circuit condition, idle condition, low humidity and humidity cycle conditions, load cycle, overload conditions, start and stop, These conditions could accelerate the performance degradation of fuel cell components and reduce the lifetime of fuel cell consequently. Combine the fuel cell vehicle actual working and Accelerated conditions establish a combined cycle condition. In order to reduce the cost of fuel cell, Non-noble metal catalyst has become a research focus. In this paper, non-noble metal catalyst Fe3/Co-TPTZ membrane electrode as a cathode catalyst, assembled in 25cm2 single cell for the single-cell performance testing. By optimizing the catalyst loading and comparison of different carbon catalysts supported non-noble metal catalyst to improve the performance of single-cell performance. The results are as follows:(1) all sorts of fuel cell life acceleration condition were analyzed and summarized. A combined cycle condition was established and can evaluate the life of MEA within a shorter time.(2) When the catalyst loading of Fe3/Co-TPTZ non-noble metal catalysts in the MEA was 4.5 mg/cm2, the highest power density 0.47W/cm2 was reached.(3) Fe3/Co-TPTZ non-noble metal catalysts supported on high specific surface carbon carriers has the better performance than that on high conductivity of carbon carriers.(4) After the steady-Voltage life test of 51.5 hours, the voltage of fuel cell with Fe3/Co-TPTZ non-noble metal catalysts as cathode dropped about 0.222V at a current density of 360mA/cm2.
